Greetings, Can anyone suggest what lensboard opening I'd need to use for a B/L Protar V 183mm f/18 lens? A Technika-type board is ideal in terms of overall dimensions. Thanks in advance, BILL Wm. Mitchell

wm,

I'm not familiar with that lens, but in similar situations I've found one of those stainless steel rulers about 6" long with a sliding pocket clip with 64ths and mms made by General invaluable for taking the odd measurement. Any good hardware store should have them on cards. I hope this helps

------------Cheers!

Bill:

I have one of those that fit perfectly inside a canham/toyo board with a copal#0 opening. I just used the flange as a lock nut. No shutter, but a lenscap works well. This lens will cover (with some hyperfocal tricks) a 7x17, although it is quite soft in the corners.
